TELESCOPE-MOUNTING FOR FIREARMS.

Application filed November 24. 1919.

To all whom it may concern:

Be it known that I, THOMAS D. J OECK, a citizen of the United States,residing at New Haven, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in TelescopeMountings for Firearms; and I do hereby declare the following, whentaken in connection with the accompanying drawings and the characters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this applicationand represent, in-

ing to produce a simple and efficient device},

escope without disturbing its relative position with respect to thebarrel of the arm.

Vith these ends in view my invention consists in a telescope mountingcharacterized by the employment of a wedge-member interposed betweenmounting members respectively carried by the arm and the telescope. Myinvention further consists in certain details of construction as will behereinafter described and pointed out in the claims.

In carrying out my invention as herein' shown, the telescope 16 whichmay be of any approved construction, is supported at its forward end ina close fitting ring 17 provided upon its lower face with an integralmounting-box 18, and at its rear end in a larger ring or annulus 19provided at its lower end with an identically similar mounting-box 20,the ring 19 being furnished with adjusting devices 21, also of anyapproved construction and forming no part of my present invention.Inasmuch as the mount ing-boxes 1S and 20 are identically alike and haveprecisely the same functions, a description of one will suffice forboth. For the purpose of this description, the rear mounting-box 20 willbe described. This box is formed in its lower face with an oblongchamber 22 rounded at its corners and having its right wall undercut asat 23, while its left hand wall is formed with an approximately paralleloutward slope 24 containing a semicircular forwardly tapering groove 25receiving an adjustable wedge in the form of a binding-cone 26 locatedat the forward end of a binding-screw 27 formed at its rear end withthreads and mounted in an extension 28 from the rear right hand cornerof the box 20. The said screw is provided at its projecting rear endwith a long, capstan-like head 29 furnished with deep longitudinal slots30 for the insertion of a coin or other convenient lever. A portion ofthe screw-threads are cut away as at 31 for the production ofretainingshoulders 32 and 33 and the reception of a retaining-pin 34which prevents the removal of the screw from the box. The threadedsection 35 thus isolated at the forward end of the screw, at the base ofthe cone 26, assists in guiding the cone.

readily demounting and remounting the telj s i ec i The said bindin-screws 27 thus mounted in the respective mounting-boxes 18 and 20co-act with front and rear mounting bases 36 and 37 secured as shown tothe receiver 38 of the gun at the opposite ends of the loading-openingtherein, each of these bases being fastened to the receiver by threescrews 40. The two mounting-bases 36 and 37 are identical in functionand substantially identical in form. Both are alike in being providedwith undercut right hand walls 41 for co-action with the undercut righthand walls 23 of the mounting-boxes 18 and 20. Both are also alike inhaving their left hand walls inwardly inclined as at 42 to correspond tothe outwardly inclined walls 24 of the respective mountingboxes. Thesaid inclined walls 42 of the mounting-bases are formed with forwardlydiminishing semi conical grooves 43 for (:0- action with the bindingcones 26 at the for ward ends of the respective binding-screws 27. Themounting-bases 36 and 87 are also formed at their forward ends withpositioning-fingers a l which co -act with the forward ends of thechambers 22 in the respective mounting-boxes 18 and 20, for quicklypositioning the same.

In order to heighten the binding action of the bindin -cones 26 in theirco-action with the semrconical binding grooves 25 of the respectivemountingboxes and the corresponding semi-conical binding grooves 43 ofthe respective mounting-bases, the fixture is prefe ably constructed asshown in Fig. 15, so that the axes of the binding cones 26 will not becoincident with the axis of the grooves 43 in the mounting-bases, theaxes of the binding-cones being above and to the right of the axes ofthe grooves in the bases so that when the binding-screws 27 are advancedin mounting the telescope, the binding-cones will tend to draw the boxes18 and 20 laterally downward and to the left of the bases 36 and 37.

The bases 36 and 37 have their rear left hand corners cut away as at 45and 46 (Figs. 9 and 12) for the clearance of the binding-cones 26 as thetelescope is mounted and demounted.

I claim:

1. A telescope mounting for firearms, having mounting-members adapted tobe respectively applied to a telescope and to a firearm, one of the saidmembers being provided with an adjustable wedge for interpositionbetween the two members to lock one to the other.

2. A telescope mounting for firearms, having mounting members adapted tobe respectively applied to a telescope and to a firearm, and anadjustable wedge carried by the mounting-member of the telescope forinterposition between the two members to lock one to the other.

st I "1 3. A telescope mounting for firearms, having mounting-membersadapted to be respectively applied to a telescope and to a firearm, anda binding-screw mounted in one of the said members and provided with abinding-cone for interposition between them to lock one to the other,the said screw having means for securing it in place and furnished witha slotted capstan-head.

i. A telescope mounting for firearms, having mounting members adapted tohe respectively applied to a telescope and to a firearm, and a bindingscrew mounted in one of the said members and provided with abinding-cone and semicircular tapering grooves formed in the saidmembers for the reception of the said binding-cone, the axis of thegroove in the member mounting the screw being out of line with the axisof the groove in the other member, whereby the two members are movedlaterally with respect to each other under the action of the bindingcone.

5. A telescope mounting for firearms, having a mounting-box adapted tobe applied to a telescope and formed in its lower face with an oblongchamber, a mountingbase adapted to be fixed to a portion of a fire-armand adapted to enter the said chamber, and an adjustable wedge mountedin one of the said parts for interposition between them whereby the twoparts are bound together.

6. A telescope mounting for firearms, having a chambered mountingboxadapted to be connected with a telescope, a mounting-base adapted to befixed to a firearm and to enter the said chamber, an adjustable wedgemounted in the box for interposition between the box and the base, and apositioning member located upon the forward end of the base foreo-action with the for ward end of the chamber in the mountingbox inpositioning the latter upon the former.

7. A telescope mounting for firearms, having a chambered mounting-boxadapted to be connected with a telescope, a mounting-base adapted to beconnected with a firearm, an adjustable wedge mounted in the box forbinding the same to the base to lock one to the other, and a positioningfinger formed upon the forward end of the base and engaging with theforward end of the chamber in the box for positioning the same upon thebase.

8. A telescope mounting for firearms, having a mounting-box adapted tobe con nected with a telescope and formed in its lower face with anoblong chamber having its right hand side wall undercut and its lefthand side wall sloped outwardly, a mounting-base adapted to be rigidlyfastened to a fire-arm and having its side walls pitched in acorrespondence with the side walls of the said chamber, and abindingscrew mounted in the said box and having a binding-cone co-actingwith semi-circular forwardly tapering grooves formed in the outwardlyinclined walls of the box and base, whereby the cone binds them togetherto lock one to the other.

9. A telescope mounting for firearms, having a mounting-box connectedwith a telescope and formed in its lower face with an oblong chamber, amounting-base adapted to be applied to a firearm and adapted to enterthe said chamber, the walls of the chamber and base being shaped tointerlock,

and a binding-screw mounted in the mounting-box and formed with abinding-cone adapted to enter forwardly tapering semicircular groovesformed opposite each other in the box and base and the said screw beingprovided at its rear end with a capstanhead for its operation.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
